Remove settings that are now in per-table trafodion-site.xml config.

For Ambari, 2.2 service_advisor over-rides the 2.1 version. This allows
possibility of single plug-in to manage 2.1 & 2.2 installs, though this is not
tested.

Simplifying the HBase config seems to have changed the timing of
HBase start-up on HDP nodes. We are trying to talk to HBase while
master is still initializing. I have added re-tries in hbcheck
to compensate.

This change-set exposed a race condition in installation.

Hbase regionserver was dying because pyinstaller is starting
regionserver before the new staging dir exists in hdfs. Prior to
simplifying the settings, installer won the race of creating hdfs
dir before regionserver looked for it.

To address this, we should just use HBase default value for.

Also remove hbase setting for hbase.client.keyvalue.maxsize from
installer. That can be added to trafodion-site.xml if needed.

Missed one file in prior commit.
